Abstract: PROBLEM TO BE SOLVED: To provide a multiwavelength etalon having susceptibility for each of a plurality of wavelengths. SOLUTION: The multiwavelength etalon has a plurality of regions 38, 39 having different refractive indices. By changing the refractive indices, the wavelength of light entering the etalon is varied, and thereby, a plurality of wavelengths between the reflection faces of the etalon are detected. By selecting specified refractive indices, the etalon shows peaks and troughs at specified wavelengths in the transmission characteristics. Or, by gradually changing the refractive index in the transition region 40 between the two adjacent regions having different refractive indices, the optical interference can be decreased.

Abstract: PROBLEM TO BE SOLVED: To provide a communication network data message management method and system by which a wandering-around subscriber can properly receive a data message with high reliability via a private communication system or a public communication system. SOLUTION: A mobile station scans control channels of a public wireless system and a private wireless system and measures a received signal parameter of at least one channel. A hybrid communication network transfers a job of the mobile station from the public wireless system into the private wireless system when the measured value is an object value of the private wireless system or over, or transfers the job of the mobile station from the private wireless system into the public wireless system when the measured value is an object value of the public wireless system or over. A job control point maintains a central database of a user protocol updated in response to the job transfer procedure and a service node again manages a data message addressed to the mobile station via any wireless system and transfers the data message to the mobile station.

Abstract: PROBLEM TO BE SOLVED: To provide a method and, a device for selecting an optimum operation state in a digital wavelength stabilization control system. SOLUTION: In this method, the value of a tuning current supplied to a multi-channel laser source is controlled. For each operation laser channel, the desired inclination of the laser source is stored as the function of the tuning current. Then, the inclination of the laser source is measured as the function of the tuning current. After that, the tuning current is adjusted until an inclination being essentially close to the desired one is measured. An operation tuning current to the laser source is set to a value corresponding to the measured inclination.

Abstract: PROBLEM TO BE SOLVED: To provide an electronic device composed of layers, which prevent the occurrence of a charge trap on the surface and have sufficient electrostatic capacity. SOLUTION: The electronic device having a capacitor structure 11 is formed by depositing a metal layer for specifying a first electrode 20 on the film of high dielectric constant materials and depositing a dielectric layer 22 of the capacitor structure 11 later on the first electrode 20. During this process, by exposing the first electrode 20 under the plasma of pure nitrogen, the partial oxidization of the first electrode 20 is prevented and the density of the charge trap on an electrode/dielectric interface is reduced. Besides, since a dielectric film 22 is passivated by nitrogen materials before forming an upper electrode 21, the mutual diffusion of the electrode and the dielectric is prevented.

Abstract: PROBLEM TO BE SOLVED: To solve the problem that an MEMS system mirror array is required which has mirror surfaces each having an effective area smaller than the steering range of the surface in order to perform signal routing, and the MEMS mirror array is necessary which requires a control signal lower than 150 V to position each mirror surface when performing the signal routing. SOLUTION: An optical element 70 to perform routing of a plurality of optical signals between a first port and a second port is provided. The optical element 70 includes a mirror array 75 having a plurality of reflectors. Each optical input signal 72 is sent out by reflectors 82 and 84 in a direction specified by control signals. The optical element 70 includes, moreover, curved mirror planes 82 and 84 which receive optical signals 72" sent out respectively from each reflector, and reflect the optical signals sent out to the first or second port, respectively.

Abstract: PROBLEM TO BE SOLVED: To provide an apparatus and a method for reducing the distortion of an input current near the zero crossing point of an input signal. SOLUTION: The power factor correcting electric converter comprises an input tracing circuit 150 connected to a power source, a rectifier 12 connected to the power source, and a filtering circuit 2 connected to the rectifier. In this case, an input detector 26 is connected to the circuit 150, and its output circuit is connected to the circuit 22. A feedback circuit 52 is connected to an input detecting node 32 and an output detecting node 50 to receive an input designation signal and an output designation signal and to generate a gating signal. The output circuit responds to the gating signal to control to switch the connection to a load. The input detector or the feedback circuit may be constituted to delay to differentiate the phases of the input designation signal and the input signal.

Abstract: PROBLEM TO BE SOLVED: To provide an optical waveguide tap which can extend the bandwidth and/or improve the resolution for a newly available optical application while keeping its cost efficiency. SOLUTION: An optical monitoring device uses the characteristic of a blazed Bragg grid to change the direction from an axis path to the inside of a detector for some optical signals. In order to increase the strength of a monitor, plural blazed Bragg grids having each peculiar characteristic are used. In particular, N pieces of grids are used for increasing the monitor's bandwidth by N times (as long as no duplication of wavelength occurs between the grids). The resolution is alternatively improved by using the narrower bandwidth and performing measurement in frequency as much as N times of the number of raw data points included in the bandwidth. The combination is attained between the extension of bandwidth and the improvement of resolution via the agreement secured between these two poles. The chirped blaze grids are also available.
